Question when idling the gauge (stock) is between normal and red line but give gas it goes to normal range. Is this an issue or this a oil regulator bad or gauge?

IIRC my old 89 used to idle around 19 psi and jump to about 45-48 psi at wide open throttle

My 94 does it to idles about 20 psi and jumps to about 45 when I get on it .
I can tell you this , that stock gauge is about worthless,, there is no way to tell from gauge to gauge what the thing is doing other than you know you have oil pressure.

Take that same engine put it in a different car of same year using the stock gauge and sending unit from the other car and the readings could be as different as night and day.

Friends don't let friends troubleshoot oil pressure issues with stock fox gauges.
